ImportError:libcublas.so.9.0:无法打开共享对象文件

Question

目前我在Gpu支持系统中安装了cuda 8.0和cuda 9.0.从keras模块导入时遇到此错误.它说像无法加载原生tensorflow运行时.我收到的错误日志是:

Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 58, in <module>

File "/usr/lib/python3.5/imp.py", line 342, in load_dynamic
return _load(spec)

ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

当我运行nvcc --version时,返回的cuda版本是,

Cuda compilation tools, release 8.0, V8.0.61

我读过一些类似的帖子,但无法解决我的问题.大多数情况下,我认为这是两个cuda版本之间的冲突.谁能告诉我如何解决这个问题？提前致谢.

你需要更新你的LD_LIBRARY_PATH,以便它指向/usr/local/cuda-9.0/lib64.将以下行添加到您的.bashrc文件(或您使用的任何其他终端)

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-9.0/lib64/

Answer 2

Tensorflow Binaries目前不支持Cuda 9.1。所以解决方案可能只是从源代码安装Tensorflow 。

在为Tensorflow安装Cuda 9.1 + cuDNN 6时，我也遇到了上述问题，这对我有用。

此外，您有以下两种选择：

1. CUDA 8.0 + Tensorflow-与Tensorflow Binaries一起使用的最稳定的CUDA版本。

2. CUDA 9.0 + Tensorflow-Tensorflow Binaries兼容的最新CUDA版本。
